Investment Project Efficiency Evaluation [PDF]

Interdisciplinary Management Research, 2006
Financial efficiency of investment project is being evaluated in this paper. It is showed that the net present value function is constant and that quota value is equal to c0 when i converges to the infinite. Optimal rates i are analyzed in certain cases and everything is illustrated through examples.

The influence of training status, age, and muscle fiber type on cycling efficiency and endurance performance. [PDF]

, 2013
The purpose of this study was to assess the influence of age, training status, and muscle fiber-type distribution on cycling efficiency. Forty men were recruited into one of four groups: young and old trained cyclists, and young and old untrained ...

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Optimized Regression for Efficient Function Evaluation

IEEE Transactions on Image Processing, 2012
In many applications of regression, one is concerned with the efficiency of the estimated function in addition to the accuracy of the regression. For efficiency, it is common to represent the estimated function as a rectangular lattice of values-a lookup table (LUT)-that can be linearly interpolated for any needed value. Typically, a LUT is constructed

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Iterative Optimization of the Maximum Directional Distance Function Model for Chinese Airline Transportation Efficiency Evaluations

Journal of Engineering
The maximum directional distance function (MDDF) model has been utilized extensively in diverse fields. However, due to practical constraints such as geographical factors, infrastructure limitations, and network scale, the theoretically improved ...
